Update:
Borrowed a Antec Truepower Trio 650w from a friend and guess what happened..
-Crysis bench still crashed
-It still scored at 10FPS less than the 9600gt when I got it to complete
-Led's on the 120's still dimmed
-and that white fill on the desktop was still there
This morning I decided to re install Vista64 just to rule out a driver/win7 issue and here's what I discovered..
-Crysis completed on the first go.
-Scored an average of 40.87FPS on the last three runs
(in contrast to 28.06FPS with the 9800GT+Win7 and 37.69FPS with the 9600GT+Vista)
-Turns out the LED's dimming was something I overlooked, the M3A78-EM has something called Q-Fan in the bios which was causing them to brighten and dim, disabled it and they are back to a steady glow.
-The white fill on the desktop I guess was also a Win7 nvidia driver issue since it hasn't happened yet this morning.
Already ordered the Corsairs and I plan on keeping them even though it turned out to be a driver issue. I'm sure I was running that little 450 at close to max which isn't very efficient from what I've read. Plus the Corsairs will allow for future upgrades Im sure.
Update #2:
Just to be thorough I put the 450w back in and it's still stable. Overclocked the 4850e back up to 3GHz and it just finished an hour (auto 1hr mix) under OCCT with no errors. Also added about 5FPS to the crysis score (45.81 average)
